based is conspecific with Espada's species from the same locality, 

 lutzi automatically becomes synonymous, with brevipollicaius. 



The third specific name proposed by Mnanda-Ribeiro, D. b. lauroi 

 from Angra dos Reis, must apparently meet the same fate, since the 

 topotypic specimens at hand, when compared with those from Tijuca, 

 show the same variability in the supranasal furrow, which is some- 

 times evident and sometimes not, and the body is not less slender 

 than that of typical hrempollicatus. These frogs in life are a perfect 

 match for the fallen leaves among which they live. When picked up, 

 they stiffen out on their backs with legs extended and "play dead" 

 for as long as one holds them captive. 



Some fully metamorphosed young frogs from Alto da Serra measure 

 only 8.5 mm. in total length. They are much paler than the adults, 

 and the pattern hardly shows. The largest adult from that locality 

 is chocolate brown; the others are gray or drab above with a brown 

 X-mark between the shoulders and a A on the sacrum. One of the 

 females from Tijuca contained about 20 eggs, each measuring 2 mm. 

 in diameter. 



Dr. Bertha Lutz has given me the following notes: "This frog 

 propagates in bromeliads, as its eggs have been found on the under- 

 sides of leaves. The tadpoles are small and black. After meta- 

 morphosing, the young frog is likewise extremely small, measuring 

 between 5 and 10 mm. The species seems to depend on bromeliads, 

 and does not jump out rapidly like the Hylas if the bromeliads are 

 disturbed. It is a mountain species."

Generic diagnosis. — Readily distinguished from Syrrhopus limbatus 

 [=PhyUobates] by its blunter snout, less vertical loreal region, by the 

 presence of a tarsal tubercle, longer tibia, and different coloration; 

 from the diskless species of Syrrhopus, it may be distinguished ex- 

 ternally by the more vertical loreal region and stouter form.
